Question

In PHP, we can pass a variable into script from the file name as file.php?key=value or file.php -key=value. Is there any equivalent option to do so in Shell Script?

I want to run the script in terminal; something like ./file.sh -key=value to pass the variable into the shell script for further processing.

Answer 1

Yes:

file.sh value1 value2

value1 and value2 will be exposed to the script in the variables $1 and $2; the whole string value1 value2 will also show up in $*.

You can use the shift shell builtin to get one variable at a time.
